IMPROVEMENT m'p ows.

Specification forming part of Letters Patent No. 127,475, dated J nne 4, 1872.

Specification describing a new and Im- -proved Subsoil-Plow, invented by HENRY GlLLETTE, of Millville, in the county of Orleans and State of New York.

My improvement pertains to a simple and novel arrangement of the adjusting and atbar B has numerous notches G in it, and is connected thereby and by the bar H to a cross-bar, I, which is made fast to the handles of the surface-plow a short distance above the ground. This bar Icontrols the depth of the cut of the share A, and will vary it by being shifted from one notch G to another. This bar I has also a notch, K, by which the bar B is prevented from shifting laterally. The bar H, which confines bars I and B together, is connected to B below the notches by a link, L, and the upper part, which is at right angles to the vertical part, passes through an eye, M, in the top of B, and is confined by a pin, N, which being taken out, the said bar H may be readily shifted forward to release the barI to allow it to be shifted, and can be as readily shifted back again to confine the said bar 1.

Having thus described my invention, I claim as new, and desire to secure by Letters Patcut-- In combination with the cross-bar I and the notched bar B, provided with the eye M, the confining bar H, and link L, substantially as shown and described.

HENRY GILLETTE.
